I soldered the wire to the spade since the tab on the circuit board was so flimsy that, had I tried to pull the spade off the tab to crimp it, I most likely would have pulled the tab off the circuit board. The fit was so loose that I was able to simply reinsert the wire into the lug. When tighening the screws on the fan motor, a wire that runs to the control circuit board fell out of the spade lug that connects it to the circuit board. When a piece of blade got flung out, I disassembled the welder to discover the problem. On top of that, the screws that hold the fan motor to the cheap plastic frame in my welder were not tightened at all so that the flimsy plastic blade would often hit the mount. Think of the fan in the cheapest, lowest quality electric space heater you have ever seen, and that will give you some idea of the fan in this welder. while most of the welder seems to be of decent quality, the cooling fan is cheap beyond belief. If you plan on welding a lot of heavier stock, such as 1/4-inch, I would go with a bigger machine.

The fact that I can weld 1/8-inch at highest power while dragging the tip (instead of pushing) without burning through suggests that the 180 amp rating is a little optimistic, but that might be the convention for these portable wire feed welders. For single pass, I would put it at no more than 3/16. maybe with a beveled joint and multiple passes. The description says this can weld 5/16-inch. Either that or somebody is pulling amperage numbers out of the air. The difference is so extreme that one must assume there is a difference in what the ratings mean between wire feed and stick welders. This welder's maximum is comparable to my stick welder running around its nominal 130 amps. My stick welder running at a nominal 180 amps is cranking out FAR more heat than this welder can even dream about. I'm not sure what the 180 amp rating means. If you need a welder in situations where time is money, or if you don't like waiting around for the box to cool down, you should look for something more robust. I have caused the overheat protection to shut the welder down multiple times when I had welds to make and was impatient to get them done. The 20 percent duty cycle rating at moderately high power is a reasonable estimate.
However, I would prefer a main on/off power switch separate from the power selector switch. This seems like a durable design with no contacts to wear out. The multi-position combination on/off and power selector switch is actually a shaft with a cam that closes one of the micro-switches around the shaft when a power level is selected. Hose and gun quality are good and comparable to the major brand name welders like this. I've had no wire feed problems with a wire feed drive that looks acceptably well designed for a welder of this class. 035 wire through it welding mostly 1/8-inch stock with small amounts of other thicknesses from 1/16 to 3/16.
